6 Claims.

My invention relates to paving bricks and more especially to pavingbricks adapted to be used in connection'with re-inforcing rods for strengthening the pavement.

A further purpose of my invention is to provide a paving brick having integral lugs ontwo opposite sides which, when aligned in the pavement will provide a suitable support for re-inforcing rods while the concrete'mixture or other tween the paving bricks.

A particular purpose of my invention is to pro- -vide paving bricks with one or more integral,

preferably wedge-shaped lugs and approximately one-fourth the way up above the bottom edge of the brick and on two opposite upright surfaces thereof and shaped to define a sort of bracket support for re-inforcing rods used in the pavement and laid between the adjacent rowsof paving bricks so that when such re-inforcing rods are supported by these lugs at their elevation; the binding agent may easily pass around the rods to fill the space between the paving bricks, leaving the 're-inforcing rods at a desirable elevation above the bottom surface upon which the paving brick may rest where the re-inforcing rod will remain to re-inforce the brick pavement after the concrete or other binding agent has been poured.

I attain the objects of my invention by the improved paving brick described in this specifi- .cation, recited in the claims and illustrated in the accompanying drawing wherein like reference numerals indicate like parts in the several figures.

Referring to the figures:

Fig. 1 is a perspective of a pavingbrick provided with integral lugs on two opposed edges for the support of re-inforced'rods. i

Fig. 2 is a detail of 'a portion of a paving brick with re-inforcing rods supported by the integral improved supporting lugs of my invention. Fig. 3 is a detail showing a portion of two adjacent paving bricks with the lugs on their adjacent edges supporting a re-inforcing rod and showing a cross rod supported by the same.

Fig, 4 is a perspective of the detail shown in Fig. 3.

Fig. 5 is a detail similar to Fig. 3 but showing the space between adjacent paving brick to be filled with a similar or other binding agent.

Fig. 6 is a. perspective illustrating a manner in which paving bricks may be marked with the supporting lugs by rollers as the ribbon of clay moves out of the die, which has its mouth shaped in a manner that will form a strip along the opposite binding agent is being poured into the space beedges'of the column of clay only to be rolled down fiatwith the claycolumn edge in'all places except where the lug is to be left.

q I shall now pointout the merits of my invention as I refer'to the figures in the drawing.

For instance, Iprefer to use my novel improveinents in paving bricks in conjunction with paving bricks which are the subject matter for patent applications which have been filed. In my present brick construction, I propose to provide a paving brick l whose horizontal dimensions are approximately square and whose depth is slightly less than approximately one-half one of its horizontal dimensions, the top surface of which paving brick is preferably rough, with two of its opposite upright surfaces provided with one or more integral supporting lugs for re -inforcing rods and its -.other"two upright surfaces wire-cut.

Thus,'it'will be noted that upright sides 2 and 3 -are provided withsupporting lugs 4 and' 5 respectively and thesesupporting lugs' are prefer- 'abl'y located approximately one-fourth of the way up above the bottom surface 6 of the paving This particular location'of the elevated posi-- 'tion of lugs 4 and 5-is preferred for the purpose ofholding' re-inforcing rods! at a'suitable level above the supporting surface 8 for the paving bricks and while reinforcing"rods *1 lay. in 'the space between adjacent 'paving bricksl dis-p posed in one direction, then the reinforcing-cross rods 9 will be laid in the space betweenadjacent bricksat right angles acrossrods 1 and sup- -po'rted'thereby." i 1 l I It will be noted in Figures'3, 4 and 5 thatlugs 4 and 5 on adjacent-faces of adjacent bricksfwill directly supportireinforcing rods'l and 9 in a 'position that will permit the concrete or binding "agent In to be'poured in'the space between adja- 1 cent paving bricks and completely fill the space: as it easily 'passes' around the reinforcing rods 1 and 9. .It is thought by-engineers that the most effective level for reinforcing rods in a'-brick -pavlement'is found to be between the center and the bottom. of". the brick and' I have therefore chosen to locate lugs 4 and 5 approximately onefourth of the way up on the paving brick from the bottom surface thereof so that when'the re-inforcing rods 1 and 9 are supported by integral lugs 4 and 5 on adjacent brick walls, these reinforcing rods will be embedded in the binding agent at the level where they will be most effective in providing the reinforcing strength for which they are intended. 1

It will be noted on lugs 4 and 5 that I have 55 of each payinggbrick unit.

preferably given these lugs a wedge shape with their top surface ll parallel with the top surface of the paving brick and with the outer surface I2 of the lugs sloping inwardly and downwardly 5 in wedge formation.

When these paving bricks are to be laid in place, it is necessary that they be aligned in both directions and in order to facilitate a satisfactory alignment it would be preferable to use a removable templet or pattern which will normally be held in place slightly above the supporting surface for the bricks and it is my purpose to give these lugs a sort of wedge shape, as il-. lustrated, so as to make it easier to slip the pa'v- 15 ing bricks into the space provided for them-Iin the templet without the lug catching onthe templet as the brick is being placed into position.

Thus the wedge shaped surface of thezlug will.

have a tendency to pass by the templet more 20 easily without catching on the templet, or spacer,

or aligningdevice that may be used.

I Engineers, working in this art, will readily recognize the fact thatreinforcing rods I and 9 will not need to be permanently carried by lugs 25 4 and 'but will only need to be supported thereby until the concrete or other b inding agent that is poured between paving bricks fills the space betweenthe adjacent paving bricks and hardens about reinforcing rods 1 and 9, giving them am- 30 ple support without any'excessive strain upon lugs 4 and 5 thereafter. I

' It will be noted in Fig.6 that when the column of clay i3 is'forced out of the mouth I 5 of die I6 then the wedge shaped nicks l! and IS in the 35 sidesof mouth l5 will produce wedge shaped side ribs l9;and 20 on the opposite sides 2| and 22 of columni,l3.

p My supporting lugs are preferably formed then by providing a side roller 23 on side 2| with wedge oshaped recess 24 therein and by providing side rollers 25 on side 22 with recess 26 therein.

V Thus, as column l3 moves out of die mouth l5, rollers 23 and 25 will roll againstthe surface 2| and 22 respectively of column l3 mashing its ribs 45 I3 and 2-,0respectively as they roll but in those places where recesses 24 and 26 of rollers 23 and 25 respectively strike ribs l9 and 20 respectively, the recessthus formedwill leave that much of the rib in place to define supporting lugs .4 and 5 50 along the side of clay-column l3.

.60 were of such form and construction as to make them contact the surface of the adjacent bricks. .Thus, in, those forms and construction of lugs, the spacers as used, :were not made in any man- ;ner that would be used as supports for reinforc- 55 ing rods as the case in this instance.

It is obvious that I would not wish to be limited to the method of forming these supporting lugs as illustrated in Fig. 6 since other methods could be practical in accomplishing this result.

I will not wish to be limited in the form of supporting lugs which I am preferably providing inforcing rods laid between the bricks in a brick pavement.

J 2.- A paving brick shaped on two opposed edges to define lugs forming horizontal ledges for the support of re-inforcing rods when the rods are .laid into the space between the paving brick rows in a pavement.

4. An approximately square paving brick, two Opposite sides of which are shaped to provide a plurality of spaced integral supporting lugs each shaped to define a horizontal ledge and each disposed nearer the bottom edge than the top edge of the brick in the same horizontal planefor the support of re-inforcing rods while a binding agent is poured into the space between adjacent paving bricks holding such rod, and to encompass t 5.A paving brick which on two of its opposite sides is shaped to provide spaced horizontally aligned integral lugs each shaped to define a.
